This design revolves around the multi-function and integration of agricultural machinery and equipment. In the conceptual design of "MO" multi-purpose modular agricultural unmanned operation system, in order to achieve different functions, different modules can be selected according to requirements. As the core of the whole system, the power module provides enough energy to support the work of different modules. At the same time, it is equipped with a variety of different modules to choose from, such as plant protection drone module, farming module, fork frame machine module, clip shovel module, harvesting module, clip stacking module, etc. These modules can be matched according to different needs to complete Different agricultural tasks. The modular design makes agricultural drones more efficient and flexible, and can meet the needs of different scenarios.
